Brief summary

This study aims to evaluate the effectiveness of a new online treatment for body dysmorphic disorder (BDD) in adolescents. BDD is an underrecognised and undertreated mental health condition, characterised by a preoccupation with perceived flaws in physical appearance. There is a paucity of research exploring the disorder among youth. In adults with BDD, cognitive-behavioural therapy (CBT) has been shown to be an effective treatment. There is some evidence that CBT can be effective for some youth with BDD, however many young people remain impaired by their BDD following treatment. Therefore, this study aims to test a developmentally-tailored CBT approach to treating adolescent BDD. The therapy will be delivered via videoconference to families, to increase accessibility to the study.

Interventions

12 weekly, 90-minute cognitive behavioural therapy (CBT) sessions will be delivered via videoconference (Zoom). The intervention will be delivered by a registered clinical psychologist (Cassie Lavell, PhD candidate). All sessions require attendance by the adolescent and at least one parent/caregiver.
